Chapter 1339

The case-related data sent by Guqi City Bureau had a full four boxes, which showed that they had really done considerable work.

However, the murderer's arson behavior indeed greatly increased the difficulty of solving the case, especially in the year back then, the fire fighting team spontaneously formed by surrounding neighbors, although successfully extinguished the fire, also objectively caused the loss of evidence.

For a case 16 years ago, without surveillance, and losing scene evidence, the difficulty of wanting to solve the case was extreme.

However, it was also because there were many neighbors at the scene, the criminal suspect was witnessed, and finally, a sketch was made.

"The murderer is tall, slightly fat, male, looks relatively young, his eyes are very fierce, his skin is darker, short hair..." Xu Taining read the description in the case file and laughed lightly: "It is consistent with Jiang Yuan's judgment. However, Guqi City Bureau still didn't find anyone in the end."

"It should be committing crimes while on the run. The murderer likely ran away after committing a crime once. This should be the main reason why he escaped successive investigations." Liu Jinghui finished reading the relevant information of the two cases in Guqi and Meiyang, and his reasoning ability gradually went online.

Xu Taining was someone who only wanted a certain answer, so he said: "Now saying it's committing crimes while on the run still needs to be proven. Judging from the situation of this case, his habit is arson after committing a crime. Then, related types of arson cases actually have suspicion. In addition, the cases in Guqi and Meiyang are both robbery and murder after entering the house. Then is it possible that some theft cases where no one was at home when entering the house were also committed by him? He can't just pick houses with people to steal, right?"

"He might not have the ability to pick locks." Liu Jinghui answered very firmly: "The case in Meiyang is not very certain. In the case in Guyang, the victim often left the door open to enjoy the cool at home because they lived in a self-built building of the unit. Robbing taxis is actually about the same. The murderer chooses those that don't need skills and have relatively high requirements for violence. Compared with robbing shop owners and the like, robbing taxis is much more convenient."

Xu Taining nodded slowly: "Tall and strong, likes to use violence to solve problems."

"It also conforms to the typical characteristics of suspects in taxi robbery cases. If they had the criminal skills of burglary, they wouldn't have to engage in taxis." Liu Jinghui said a very cruel truth. Even if it is a crime, those with criminal skills also obtain higher returns with lower risks.

"So the murderer first looked for some convenient opportunities, entered people's houses to commit violent crimes, then there was no need to start killing people from the beginning, right?" Xu Taining asked the question.

Liu Jinghui made an "um" sound: "If you want to ask me how the murderer grew up step by step, this is a criminal profiling type of thing. What I can answer is that after the murderer started killing people, he consciously chose to commit crimes while on the run. Otherwise, with the traffic conditions 15 years ago, or even longer ago, it is easy to commit crimes across cities, but committing crimes across provinces, and it is national-level committing crimes? If it is not a conscious behavior, it is not easy to explain."

Liu Jinghui put himself in the murderer's shoes and considered: "Every time he commits a crime, first of all, it is a fugitive identity, and secondly, he has to fence. Being able to endure not committing crimes continuously and fencing at once, but running away first, can be considered to have some brains. By the Li Huimin case, it can be regarded as another crime escalation. He was facing two victims, and also coerced the victim to drive thousands of miles. This process is very difficult to grasp. Of course... he might also have a gang. Taxi robbery cases often have gangs."

Typical characteristics of a certain type often have their internal causes inside. Just like far-away prostitution and near-by gambling, taxi robbery is also best in a team cooperation mode, not only because taxi drivers were robbed too much in the past and easily hid weapons to fight back, mainly to deter the driver, making it easier for multiple people to rob, making them give up resistance, and also reducing the cost of robbery personnel.

"Committing crimes while on the run was indeed a good idea back then. The problem of gangs also needs to be considered." For Xu Taining, committing crimes while on the run is also very troublesome. In fact, for any criminal policeman, committing crimes while on the run is a case that is relatively difficult to handle. Detection often relies on luck and interrogation.

When the conversation reached here, the two looked at Jiang Yuan at the same time.

Jiang Yuan raised his head at the right time. He had been scanning photos on the pad. At this time, he asked Wang Chuanxing to put out several marked photos and said: "I just scanned the other several cases evaluated as C, and among them, I found a footprint that conforms to the suspect's characteristics and can be certified as the same."

"Let me see. Which one?" Xu Taining asked immediately.

"The case in Liyuan." Jiang Yuan asked Wang Chuanxing to print the data and synchronized the explanation: "It is also killing and burning the corpse, but it is in the wild, using gasoline. The corpse was burned very severely, and there was no vehicle at the scene, but the footprints were baked hard and left behind."

"The Li Huimin case is also in the wild." Liu Jinghui added, frowned slightly, and said: "This murderer, he should have been experimenting back then."

"Researching killing?" Xu Taining asked.

"About the same meaning. Some murderers like to use the same killing method, and some like to experiment."

"Experimenting also has risks." Xu Taining didn't wait for the printing, asked someone to take the PAD, and also began to flip through it.

For a time, the scene was the sound of flipping pages, or PAD, or paper documents.

"Bajiang Burning Corpse Case, that is the case with B-level similarity. I think in the investigation stage, it can also be temporarily determined as one of the same series of cases." Liu Jinghui spoke at this time, and then began to say some fine information between the lines to reason that the murderer was the same.

Jiang Yuan and Xu Taining listened for a while and expressed approval. Thus, the Li Huimin case was upgraded to a series case, involving locations in Meiyang, Guqi, Liyuan, Ningtai, and Bajiang, totaling five cases.

All five cases were murder cases, but except for the case in Ningtai County, the other four cases did not burn the car. However, the cases in Guqi and Meiyang were entering the house, and the cases in Liyuan and Bajiang were burning corpses in the wild. Although it was not determined what the means of transportation was, the possibility of carjacking was still very high.

Xu Taining then arranged for people to follow up on the corresponding cases normally, and also sent people to Liyuan and Bajiang to investigate the lost car cases within the corresponding time.

At the same time, Xu Taining also notified the information that the murderer was 1.8 meters tall, 180 jin, and currently 42 to 46 years old. This piece of information received multiple verifications. Up to now, it was another clue, and compared with murder cold cases, burglary, and carjacking cases from more than ten years ago, it might be possible to discover new clues again.

It is simple to say but difficult to do, unless there are many people.

One order from Xu Taining, placed in any city or county, requires at least several people to investigate. Those who have spare energy and ideas might have to send more than ten people to search through old papers. Roughly calculated, this is the investment of hundreds of police forces.

If it were an ordinary special task force, with a total of twenty or thirty police officers, even if there were such clues, at most one county or city would send two people to follow up, and they would have to beg for the other party's cooperation, and it would be best to borrow one or two people to accompany them. Even so, it is very normal to run to dozens of counties and cities for several months without sleeping or eating.

Some special task forces, pursuing these two clues, are considered the end. If they can't catch up, they should be about to end.

But for Xu Taining, these are just a section of the long journey. He also collected footprint clues from many parties, in order for Jiang Yuan to have new breakthroughs. On the other hand, he also specially sent people to re-sort the timeline and study the murderer's escape route.

Most importantly, Xu Taining directly restarted the four murder cases in Meiyang, Guqi, Liyuan, and Bajiang.

The two cases in Liyuan and Bajiang were both burning corpse cases in the wild. The main clue was the corpse. The local investigation was relatively deep, but they didn't have corresponding suspect identity information. The two cases in Meiyang and Guqi were both robbery and murder after entering the house, focusing on investigating the situation of fencing, and also used special information and other news. But if we consider that these four cases are actually part of the series of cases, it is easy to think that the murderer will not only adopt the method of fencing in other places, but may also fence across provinces.

In the environment back then, it was too difficult to investigate.

But for Xu Taining, these are all new clues.

The special task force is like a heavy shield tunneling machine, traveling in the dense rock mass of the vast mountains, seemingly unstoppable, able to go anywhere, but in fact, it must go through careful planning and exquisite design to achieve the goal. And the countless gears rotating rapidly inside it are ultimately expressed on the outside, only to the extent of a few meters per hour.

Clues gathered rapidly, then were re-distributed by Xu Taining, then gathered again...

A few days later.

Jiang Yuan got up early to go to work and saw a familiar figure standing at the gate of Anwan City Bureau.

"Director Jiang." Wei Zhengguo saw Jiang Yuan, didn't wait for him to speak, and hurriedly said: "I know I am not suitable to participate in the special task force's action, but I also hope that the special task force doesn't need to avoid me. I rented a house nearby to live in. If the special task force has anything to ask, I can provide it at any time."

After speaking, Wei Zhengguo didn't wait for Jiang Yuan's answer and turned away.
